Summary
media: pvrusb2: fix memory leak in pvr_probe
Details

In the Linux kernel, the following vulnerability has been resolved:

media: pvrusb2: fix memory leak in pvr_probe

The error handling code in pvr2hdwcreate forgets to unregister the v4l2 device. When pvr2hdwcreate returns back to pvr2contextcreate, it calls pvr2contextdestroy to destroy context, but mp->hdw is NULL, which leads to that pvr2hdwdestroy directly returns.

Fix this by adding v4l2deviceunregister to decrease the refcount of usb interface.
